 beständig geerdet. Der andere Kontakt genannten Tasters ist mit der Stromquelle 22 verbunden. Wenn genannter Taster niedergedrückt ist, so ist der Magnet des Relais 14 aus dem Stromkreis ausgeschaltet. Damit nun der Wellenstrom, der der Streckenleitung an einer Geberstation übertragen wird, den Klopfer des Gebers in Tätigkeit setzen kann, ist ein Elektromagnet 24 an jeder Station vorgesehen, der selbst in dem Stromkreis des Wechselstromes an der Geberstation sich befindet. Dieser Elektromagnet muss bei seiner Erregung durch den fortgehenden Wechselstrom seinen Anker von dem normalen Kontakt 25 abziehen und den Klopferstromkreis, der auch genannten Anker mit seinem Kontakt enthält, öffnen, so dass der Geber sein eigenes Sendesignal erhält.

   Damit nun ein Ton, der durch das Freigeben des Klopferankers hervorgehoben wird, sich vollständig von dem Ton unterscheidet, der durch dessen Anziehung hervorgerufen wird, wird ein Tondämpfer 26 angeordnet, der mit der Ankerschraube 27 bei der Anziehung genannten Ankers in Berührung kommt.

 permanently grounded. The other contact, called the button, is connected to the power source 22. When said button is depressed, the magnet of the relay 14 is switched off from the circuit. So that the wave current that is transmitted to the line at a transmitter station can set the transmitter's knocker in action, an electromagnet 24 is provided at each station, which is itself located in the circuit of the alternating current at the transmitter station. When excited by the continuous alternating current, this electromagnet has to pull its armature off the normal contact 25 and open the knocking circuit, which also contains the armature with its contact, so that the transmitter receives its own transmission signal.

   So that a tone that is emphasized by the release of the knocking anchor is completely different from the tone that is caused by its attraction, a sound damper 26 is arranged which comes into contact with the anchor screw 27 called anchor during the attraction.

PATENT-ANSPRUCH : Schaltung für Wechselstromtelegraphen, bei welcher der Klopfer jeder Station von einem Streckenrelais (14), dessen Kern aus einem permanenten Magneten besteht, betätigt wird, der unter dem Einflusse eines das Relais durchfliessenden Wechselstromes eine Kontaktmembran in Schwingungen versetzt und hiedurch einen lokalen Stromkreis unterbricht, dadurch gekennzeichnet, dass das Streckenrelais fol4) der Geberstation beim Niederdrücken des Tasters (23) ausgeschaltet wird, während gleichzeitig ein Elektromagnet (24) eingeschaltet wird, welcher die Unterbrechung des Lokalstromkreises an dem Kontakt (25) bewirkt, um den Klopfer der Geberstation zu betätigen. PATENT CLAIM: Circuit for alternating current telegraphs, in which the knocker of each station is actuated by a line relay (14), the core of which consists of a permanent magnet, which, under the influence of an alternating current flowing through the relay, sets a contact membrane into oscillation and thereby interrupts a local circuit characterized in that the section relay fol4) of the transmitter station is switched off when the button (23) is pressed, while at the same time an electromagnet (24) is switched on, which causes the interruption of the local circuit at the contact (25) in order to actuate the knocker of the transmitter station.
